Under all speeds and throttle levels, the Flashpaq can boost horsepower for quicker speed, torque for more towing ability, or increase fuel economy as you choose. Varying factory settings for fuel/air mixtures, timing, fuel injector flow, throttle responsiveness, and automatic transmission shift points produces amazing results, and the Flashpaq delivers for a price that’s hard to beat.

Transmission shift points can also be revised to shift at higher or lower rpms, or controlled manually by you. If your transmission is more advanced and provides varying levels of shift firmness, those can be adjusted as well. Diagnostic trouble codes for any vehicle system can be retrieved, stored, and cleared whether your check engine light is on or off. The Flashpaq is also equipped to recalibrate your speedometer for larger tire sizes, change the factory setting that limits your vehicle’s top speed, and adjust engine rev cutoff to whatever you choose. The Flashpaq unit is backed by a 1-year manufacturer warranty against manufacturing defects.

Founded in the United Kingdom as P.J. Detection Techniques in 1977, Superchips was originally involved in racing and became one of the first tuner companies to gain in-depth expertise on modifying engines equipped with electronic fuel injection systems. As engineering expertise grew on a variety of fuel systems and engine types, the company first debuted a line of power-enhancing performance products to the consumer market in England, then worldwide. After changing their name to Superchips in 1991, the company established itself in the United States a year later. The company grew to specialize in hand-held programmers and today remains on the cutting edge of turning modern computer-controlled vehicle functions into creative tuning applications. In 2005, Superchips was acquired by MSD Performance and became affiliated with MSD Ignition, Edge Products and Racepak parts. Today, Superchips USA is based out of Sanford, Florida and performs all production in the United States.

I bought this for only 2 reasons. To reset my speedometer because I had installed oversize tires, and the Mileage Saver feature. Visually I can see and feel my speedometer is more accurate, and driving through one of roadside radar speed limit signs confirms it. Also, my mileage went for 15+ to 17+. Well worth it for just those two features.

The Flashpaq Tuner has done what it was reported to do. The installation was relatively easy for a novice like myself. I have clearly seen an improvement in fuel economy, and it has helped me to be more aware of my driving habits. I am looking forward to towing my son's boat. Thanks for the opportunity to take this review. Pat
